SICQ Coping and the Health-Related Quality of Life and Recovery of Critically Ill ICU Patients: A Prospective Cohort Study

Background: The coping styles of the Sickness Insight in Coping Questionnaire (SICQ; positivism, redefinition, toughness, fighting spirit, nonacceptance) may affect the health and recovery of hospitalized critically ill patients.

Research question: Do the SICQ coping styles of hospitalized critically ill patients relate to the patients health-related quality of life (HRQoL) and recovery?

Study design and methods: A prospective cohort study was conducted in a single university-affiliated Dutch hospital. Participants were critically ill adult patients admitted to a mixed medical-surgical ICU (start: n = 417; pre-ICU: n = 391; hospital discharge: n = 350; 3-month follow-up: n = 318; 6-month follow-up: n = 308; 12-month follow-up: n = 285). Coping was recorded with the SICQ pre-ICU and at discharge. HRQoL was measured with the SF-12 pre-ICU, at discharge, and 3, 6, and 12 months after discharge. Indicators of recovery were ICU and hospital length of stay, discharge disposition, and mortality. Correlation and regression analyses were used for data analysis.

Results: Positivism (r = 0.28-0.51), fighting spirit (r = 0.14-0.35), and redefinition (r = 0.12-0.23) associated significantly (P < .05) with mental HRQoL after discharge. Furthermore, positivism associated positively (P < .01) with physical HRQoL (r = 0.17-0.26) after discharge. Increase in positivism (r = 0.13), redefinition (r = 0.13), and toughness (r = 0.13) across the period of hospitalization associated positively (P ≤ .05) with mental HRQoL at discharge. Pre-ICU positivism associated with hospital length of stay (ρ = -.21, P ≤ .05) and hazard for death (HR = 0.57, P < .01) and had a unidirectional effect on mental HRQoL (β = .30, P < .001).

Interpretation: SICQ coping is associated with long-term mental HRQoL, hospital length of stay, and hazard for death among hospitalized critically ill patients.
